Title: Improvements relating to the coating of metallic surfaces
IPC: C23C22/73
Filed: 1959-05-21
Abstract: In a process for forming a protective coating on a metallic surface by treatment with an aqueous coating composition which interacts with the surface or with an integral coating thereon, the surface is preheated and the coating composition is applied in the form of finely-divided particles, the temperature of the surface and the size and quantity of the particles being so correlated that the particles dry in the position where they first strike the surface.  The surface is preferably maintained at at least 135 DEG F. during application of the coating composition, being heated either before or both before and during the application. The surface may be heated after coating to complete the reaction or cure the coating.  The particles are applied by an atomizing gun and preferably have diameters in the range 15-500 microns. Two or more layers of the coating composition may be supplied. Bare metal surfaces, e.g. of iron, mild steel, stainless steel, zinc, copper, aluminium, magnesium, brass or bronze, may be coated: alternatively, surfaces already coated with e.g. phosphate or oxide layers, may be treated.  Coating compositions which may be used are acidic solutions of zinc phosphate, manganese phosphate, iron phosphate, calcium phosphate, alkali metal phosphates, oxalic acid or oxalates, amine phosphate solutions, dispersions or emulsions of lubricating phosphates, e.g. lauryl phosphate, mineral acid solutions, acidic solutions containing sulphide or sulphite ions, acidic rinse solutions containing chromic acid or dichromates, acidic or alkaline metallic chromate rinsing solutions, and solutions containing hexavalent chromium and organic polymeric material e.g. polyvinyl alcohol or polyacrylic acid.  Many examples are given of such compositions. Specifications 840,890 and 845,259 are referred to.

Title: Automatic compressed air brake controlled electrically and by compressed air, particularly for trains composed of several motor vehicles
IPC: B60T13/66
Filed: 1920-06-26
Abstract: 169,032. Rushen, P. C., (Knorr-Bremse Akt.-Ges.). June 26, 1920. Fluid-pressure. - Relates to compressed-air brakes which can be controlled either pneumatically or electrically and in which a main reservoir is connected to the brake cylinder both in electric and pneumatically controlled applications, so that the maximum braking pressure remains the same irrespective of the stroke of the piston and consists in connecting the electric application valve to a pipe which connects the main to an auxiliary reservoir. The main reservoir e is supplied through a reducing-valve d from the reservoir c, which is charged by the compressor. The auxiliary reservoir is supplied from the reservoir e through a reducing-valve g and a constriction h in the pipe g<1>. This constriction mav be provided in a non-return valve which permits a free flow of air out of the reservoir i. Air can flow past the usual groove in the triple valve piston k to the train-pipe p, which is normally not connected to the main reservoir through the driver's valve. If there are any trailer vehicles in the train, the auxiliary reservoirs on these are supplied by the train-pipe from the main reservoirs on the motor-vehicles. The constriction h prevents the occurrence in the auxiliary reservoir of a pressure sufficient to move the triple valve to application position when the reservoir is feeding the train-pipe. The brakes can be applied by energizing the valve l, thereby connecting the reservoirs e and i to the brake cylinder o through the double-check valve n, the supply from the reservoir i being substantial only if the constriction at h is provided in a non-return valve. The brakes can be released by energizing the valve m. The brakes can also be applied by reducing the train-pressure to actuate the triple valve k, the pressure in the reservoir i being maintained at the normal value through the connection g<1>. Release after a pneumatically-controlled application is obtained by admitting the full pressure in the reservoir e to the train-pipe through the driver's valve, to return the triple valves. To permit release of the brakes by train-pipe pressure control after an application by the valve l, the valve n is provided with a light spring urging it to the right, so that by initiating a pneumatically-controlled application after an electrically-controlled application the valve n is returned to the position in which it connects the brake cylinder to the triple valve through which the cylinder exhausts when the train-pipe pressure is restored.

Title: Coated granules
IPC: E01F9/04
Filed: 1962-05-08
Abstract: 1,000,184. Coated granules. MINNESOTA MINING & MANUFACTURING CO. Drawings to Specification. Heading B6G. Freely-flowable granules comprise non-friable core members adherently coated with non- tacky solid thermo-adhesive particles. The solid particles may comprise transparent microspheres associated with underlying specular reflectors. The core is preferably spheroidal and are usually at least 5 mils in diameter. They are first coated with a tacky resinous binder such as epoxy resin and hardener or a phenolaldehyde addition polymer. The core members may be glass beads, and the adhesion thereto of the tacky coating may be improved by treatment with e.g. vinyl trichloro-silane. The cores are then treated with a solid resin powder to prevent clumping. Metal, e.g. silver-coated glass microspheres of size from about 10 to about 250 microns are then applied to the coated granules by pouring the granules into excess of the spheres and passing the mixture on a vibrating conveyer into a heating zone, where the non- tacky particulate resin on the core members is softened and the microspheres become embedded therein. Excess beads are removed by screening. The exposed silver coating on the microspheres is etched off by means of potassium dichromate and concentrated sulphuric acid. The resulting granules may be applied on to a paint film as upon an aircraft runway to render the paint light-reflecting. Specifications 556,935, 712,784 and 857,334 are referred to.
